“This guy passed away today,” she wrote on Instagram with a picture of her dog, Chunk. “Thank you to everyone who has sent so many goodies, doggy treats, toys, clothes, paintings, stuffed animals, and everything else over the years. He loved being famous and getting recognized, especially without me.”

In her tribute post the talk show host shared a sweet memory of their time together, writing, “I was paddle boarding on the Hudson River in upstate NY and he was following me on the shoreline by the trees, and finally jumped in and swam a quarter of a mile to get on my paddle board with me.”

Although it’s unclear as to how Chunk passed, a previous Instagram on Handler’s page shows the dog at a physical therapy session.
